LS-1340 Series
Cylinder-bed, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Hook
Description
With its larger needlebar stroke, larger lift of the presser foot, and newly adopted double-tension mechanism, the machine sews beautifully with thick threads (low count thread) and at higher thread tensions. This allows the machine to sew a broad range of heavy materials. * The LS-1340 is provided with a single-tension mechanism. |
Compared with the elliptical feed, the rectangular feed helps reduce gathered stitches. |
The ratio of alternate vertical movement remains unchanged even when the material thickness changes. |
The slimmed-down throat plate easily responds to the sewing of small tubular articles with diameters as small as φ40mm. This enhances the machine's ability to smoothly sew not only bags and shoes, but also small articles such as wallets. |
The throat plate and feed dog are provided with a gauge that offers an excellent capability for the sewing of sharp curves. These gauges are especially useful for the sewing of curves of bags and leather cases. |
|
With just a light press on the one-touch type reverse feed button, reverse feed stitching is actuated. |
The machine handles thread counts from #30 to #5. Its highly rigid thread trimming mechanism cuts the thread without fail. The machine can be applied to a broad range of sewing processes, including the sewing of bags. |

Since the needle thread-tension-release solenoid is fitted on the rear face of the machine head, the area around the needle entry is easily viewable. This substantially improves the operability of the machine. |
